- Abstract
- Numerical methods are the norm in modern structural engineering practice Models based on elasticity theory offer powerful methods to analyse complex structural behaviours and accurately predict probable deformation behaviour. Numerical methods in general and particularly finite element methods offer great numerical accuracy. Yet the tendency is that with increased accuracy come the downside of decreased design capabilities. This is reflected in construction industry practice, where analysis by convention follow design in a largely linear process.

- The solutions to ecological sustainability are found in thermodynamics, material science and structural mechanics. Engineers need methods to get creative with their knowledge and participate in design collaborations effectively. Graphic statics offers one such opportunity for structural mechanics.
